The JBX42533 ST/APC to ST/APC duplex singlemode fiber patch cable represents a premium solution for demanding network infrastructure applications requiring extended cable runs. At 60 meters in length, this cable eliminates the need for multiple shorter segments, reducing connection points and potential signal degradation. Key Technical Specifications: This duplex cable features dual 9/125 singlemode fiber strands with G.657.A1 glass composition, optimized for long-distance transmission at 1310nm and 1550nm wavelengths. The cable delivers exceptional performance metrics: attenuation of 0.25 dB/km at 1310nm (0.35 dB/km at 1550nm), insertion loss of ≤0.35dB (0.15dB typical), and return loss exceeding 20dB. These specifications ensure minimal signal loss and maximum data integrity across your network. Robust Construction: The 1.8mm outside diameter with yellow OFNR-rated (Riser Rated) jacket provides enhanced durability while offering excellent visibility in cable trays and conduit. The Type A to B crossover polarity configuration is the industry standard for duplex patch cords, ensuring seamless integration with existing network infrastructure. Compliance & Certification: Fully TAA (Trade Agreements Act) compliant and RoHS/ELV certified per EU directive 2002/95/EC, making this cable suitable for government projects and environmentally conscious organizations. Tested per ANSI/TIA/EIA-455-171-A-2001 standards. Applications & Use Cases: Ideal for telecommunications facilities, enterprise data centers, campus networks, and high-speed data transmission requiring reliable long-distance connections. The extended 60-meter length reduces installation complexity and maintains signal quality. Customization Available: If 60 meters doesn't meet your exact requirements, custom lengths are available. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty.
